“He’s a young fighter, so the main thing you have to worry about with young fighters is that they’re really explosive,” Voelker told MMAjunkie Radio. “They feel like they’re Superman. They’re explosive off the bat. But after that short burst of energy, they’re going to realize, ‘Oh, I’m a tough, grueling fight, and this isn’t going to be easy.'”

The resolution comes at a critical time for the veteran. Voelker, who works in construction in addition to fighting, is in danger of being released from his contract if encounters another setback. So far, he is 0-2 in the promotion after being transferred from the now-defunct Strikeforce, where he won three straight.

But he said that unlike earlier appearances, he’s had a full training camp to prepare for the fight against Macario.

“Of course there’s pressure,” he said. “I’ve got the feeling if, for some reason, I was to lose this one, I’d be done. So the pressure is there for this fight.

“But it doesn’t matter. I’ve trained so hard for this fight. It’s impossible for him to beat me. There’s no way he’s got a chance against me. He’s a tough, strong fighter, but I’m tougher and stronger.”

That’s not to say that Voelker is overlooking Macario, who is best known for his turn on “The Ultimate Fighter: Brazil 2.” But he doesn’t think there is much that the Brazilian brings to the table that he hasn’t seen.

“There’s a lot of fighters that do what he does,” Voelker said. “I’m not looking past him. Anybody has that shot to beat anybody. But he doesn’t impress me in a whole lot of ways.”

Macario’s run on “TUF: Brazil” came to an end after a strong first round against Leonardo Santos. In the second frame of their fight for the reality-show crown, Santos surged back with some slick work on the ground and forced a submission.

While Voelker prefers to finish fights with his fists, he’s got a good idea of how his opponent responds to pressure.
